Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
SQL injection vulnerability in versions prior to 4.7.0 of Quiter Gateway by Quiter. This vulnerability allows an attacker to retrieve, create, update and delete databases through the suceso.contenido mensaje in /QMSCliente/Sucesos.action.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

SQL injection vulnerability in Quiter Gateway versions prior to 4.7.0 allows remote attackers to execute arbitrary SQL commands through the 'suceso.contenido mensaje' parameter in the /QMSCliente/Sucesos.action endpoint. This enables complete compromise of the database, including read, create, update, and delete operations.

MitigationUpgrade Quiter Gateway to version 4.7.0 or later; implement parameterized queries and input validation on the affected parameter to prevent SQL injection.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Confirm Quiter Gateway installation
    Identify if Quiter Gateway software is deployed in your environment by checking your application inventory, installed software list, or service documentation.
    Affected if Quiter Gateway is present in your environment
  2. Determine installed version
    Locate the version information for your Quiter Gateway installation using your system's standard method (such as checking the application metadata, version file, admin console, or service banner). Compare your installed version to 4.7.0.
    Affected if Installed version is earlier than 4.7.0
  3. Verify vulnerable endpoint exposure
    Check if the /QMSCliente/Sucesos.action web endpoint is accessible in your environment by reviewing your web server configuration, exposed URL mappings, or by attempting to access the endpoint if you have authorization.
    Affected if The /QMSCliente/Sucesos.action endpoint is publicly or internally accessible
  4. Confirm parameter availability
    If the endpoint is exposed, verify that the 'suceso.contenido mensaje' parameter is accepted by the endpoint through normal application usage patterns or API documentation.
    Affected if The 'suceso.contenido mensaje' parameter is processed by the endpoint

You are affected if Quiter Gateway version is below 4.7.0 and the /QMSCliente/Sucesos.action endpoint handling the 'suceso.contenido mensaje' parameter is accessible in your environment.

dbcve · scoped
Upgrade available Upgrade to 4.7.0 or later
Fixed in 4.7.0
Interim mitigation

Upgrade Quiter Gateway to version 4.7.0 or later; implement parameterized queries and input validation on the affected parameter to prevent SQL injection.

Recommended fix Moderate confidence

4.7.0

  1. Identify all deployed instances of Quiter Gateway in your environment
  2. Check the current version of each Quiter Gateway installation
  3. If the version is less than 4.7.0, plan and schedule an upgrade to version 4.7.0 or later
  4. Perform the upgrade following the vendor's standard upgrade procedure
  5. After upgrading, verify the new version is 4.7.0 or higher
  6. Validate that the /QMSCliente/Sucesos.action endpoint is no longer vulnerable to SQL injection by reviewing access controls and input validation
